Abstract Background Whether healthy older people can benefit from cognitive training (CogTr) remains controversial.This study explored the benefits of CogTr in community dwelling, healthy, older adults and compared the effects of single-domain with multi-domain CogTr interventions.Methods A randomized, controlled, 3-month trial of CogTr with double-blind assessments at baseline and immediate, 6-month and 12-month follow-up after training completion was conducted.A total of 270 healthy Chinese older people, 65 to 75 years old, were recruited from the Ganquan-area community in Shanghai.
Participants were randomly assigned to three merlin wizard costume groups: multi-domain CogTr, single-domain CogTr, and a wait-list control group.Twenty-four sessions of CogTr were administrated to the intervention groups over a three-month period.Six months later, three booster training sessions were offered to 60% of the initial training participants.The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS, Form A), the Color Word Stroop test (CWST), the Visual Reasoning test and the Trail Making test (TMT) were used to assess cognitive function.
Results Multi-domain CogTr produced statistically significant training effects on RBANS, visual reasoning, and immediate and delayed memory, while single-domain CogTr showed training effects on RBANS, visual reasoning, word interference, and visuospatial/constructional score (all P Conclusions Cognitive training can improve memory, visual reasoning, visuospatial construction, attention and neuropsychological status in community-living older people and can help maintain their luce chandelier functioning over time.Multi-domain CogTr enhanced memory proficiency, while single-domain CogTr augmented visuospatial/constructional and attention abilities.Multi-domain CogTr had more advantages in training effect maintenance.Clinical Trial Registration Chinese Clinical Trial Registry.
